To all whom t may concern:

Be 4it known that I, PIERRE PLANTINGA, a citizen of the' United States, resident of Cleveland, `county/of- Cuyahoga, and VState of Ohio, have invented new and useful Ime provements in :Coke-Ovens, 'of which the following is a speciiication, the principle-of the invention being herein explained `and the best mode in which I :have ycontemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to vcoke ovens, and

particularly to an improved structure of the walls thereof. The subject-mattervof this invention Ahas been divided out from my pending appli'cation,.Serial No. 111,521.

The object of the invention is to provi yle a coke oven installation in which the Cracking df adjacent walls, due tothe expansion and contraction, is reduced to a minimum.

rPhe annexed drawings and the following description set forth in ydetail certain; means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be employed.

In said annexed drawings: l Figure 1 represents a section of a fragmentary portion of a coke oven installationv embodying my invention, taken in 'the planes indicated" by the lines I--L in Fig. 3, the greater portion of such planes being parallel with the floor of the retort; Fig. v2 represents a transverse vertical `section taken in the plane indicatedb-y the line II-fII, in Fig. 1 and viewed in the direction indicated by they arrows; Fig. 3 represents-a transverse vertical section taken in the 'plane indicated 'by the line :HI-e111, in Fig. 1 and viewed in the direction indicated by the arrows; Fig. 1 represents a fragmentary transverse vertical section taken in the. plane indicated by the line IV-*V, in 1 and viewed in the direction indicated by the arrows.

Referring generally to some elements of my-.improved coke oven, with which the specic improvements herein claimed -are utilized, there is provided an outer casing orl housing 1 of the 'requireddimensions,y such dimensions "'depending upon the number and size of the colring chambers, as will be readily understood. Formed Within the casing 1 are a lplurality of inclined coking chambers- 2 whose sides, top and bottom are formed of suitable tile '3 abutting andjoined with each Specification of Le-tter'siiate'nt. luayf 1919*.,Y di

other, the joints formed the tile elements i running in the gene-ral'direction, that v-is'-,

parallel with thedirection'of inclination of the chambers, and at right angles thereto,

as shown in Figs. v2-and- 3. The upper end of each such coking chamber 2'fis closed by i means of a suitable removable closure 4 and communicating with said'upper or rear `end is a charging duct 5 closed by a suitable closure 6, as shown in Fig. 2.- Each coking chamber 2 -is furthermore provided with a vertical gasjtake-oif flue 7 connected with a suitable pipe 8 for conducting the gases formed Sto the desired point.- The `vlower vor frontend of each chamber v2 is closed by means of a suitable removable shown in Figs. Vl and 2. Y

The :coal is charged through theicharging duct `5 into the chamber'and when the lcolc ing operation is complete, the closures L)randa Q-are removed and lthe contents removed by pushing the same from the l rear out from the front end, Vas will be readily understood.

Adjacent to eachy side of' each coking chamber 2 isa set of parallelV combustion chambers 10, these chambers -alsobeing inclined and having a direction ofinclination parallel with l that of the general 'direction of inclination of the coking chambers f2, as shown-in Fig. 3. The specific structure closure 9, as l ofthe YWalls of these combustion chambers 10, in `combinationwith a' certain relative structure ofpartition Walls hereinafter more fully described, forms the subjecbm'atter of Ithis application.

Referring'y againfgenerally to certain fea- I tures of this co'lre, oven, particularly de.- scrifbed and #claimed in saidpendingapplicationNo. 111,521, there is provided a vertical l-ue 11 with which lthe upper or vrear ends of cachothe combustion chambers 10 comprising a 'given set communicate, which flue 11 in turn communicates with 'a horizontal -flue 12, which leads to the stack (not shown). This flue 12 receives andtakes od the gases of combustion formed in theV com-A 'n bustion chamber. TheV eliclux ofthe lgases of combustion fromthe'luesl'l and l1 2 is valve regulated, as plainly sho-wn and described ln said pendingapplication;` "There isfprolos vided ta longitudinalairduct 13, Figs. 2 and? y 3,' which connnunicat'es by 'means of horizontal passages 14: with a vertical duct 15. The l air ductlis usually"connectedwith a -re-f superato? (Het/Shown), sich, as, iserdinarly provided in this 'class of "devicesfas willbe readily understood. One such duct 15 is located between the front ends of each two adjacent sets of combustion chambers 10, as shown in Fig. 1, and communicates with a plurality of air inlets 16, Fig. `3, one of which is located adj acently to the lower end of each combustion chamber. These air ducts 16 are controlled by adjustable valves so that the influx of air at these points is capable of regulation. inlet 17 is provided, as shown in Fig. 3, which's also valve controlled. This lastnamed air inlet-17 communicates directly with the horizontal passage 14. kOpposite the lower end o-f each set of combustion chambers 10 is a vertical iiue 18, whose lower end communicates with a gas duct 19 which itself is connected with a suitable source of fuel gas (not shown).

The device as above described operates as follows, as has been explained in detail and claimed in said pending application:

The gas from the duct 19 flows upwardly into the duct 18 and becomes mixed with air from the inlet 17. Additional air from the inlets 16 is mixed with the mixture of air and gas first formed and is then burned. These gases of combustion pass up through the combustion chambers 10 and flow out through the flues 11 and 12. During such passage they heat the sides of the coking chambers 2 and effect the coking operation.

Between each two adjacent sets of combustion chambers 10 is disposed a partition wall 20 contiguous to the tile 3, that is, abutting the walls of the combustion chambers, Figs. .1 and 4f, whose construction will now be described in detail, and forms, in combination with the relative construction and disposition of the side walls of the combustion chambers 10, the subject-matter of this application;

This partition wall 20 is built of suitable brick and the joints are made to run horizontally and vertically. It will thus be seen that the joints of these partition walls and the joints of the adjacent side walls of the combustion chambers 10 lie in planes which intersect one another, the arrangement, therefore, being such that the adjacent joints break with each other. By means of this arrangement, the cracking of these adjacent walls is minimized, as will be understood.

Attention will also be directed to the fact that the side walls of the coking chambers 2 diverge and that this divergence with respect to all the walls, as plainly shown in Fig. 1, is in the same direction. A part of the partition walls 20, as is shown in said ligure, are rectangular in horizontal section, but certain of these walls, as for instance walls 21, are built so that their sides diverge in the direction opposite that of the direction A An additional air of divergence of the coking chambers 2, as shown. By Yproviding such a wedge-shaped partition wall 21 at suitable intervals also contiguous to the walls of the adjacent combustion chambers, the rectilinear form of the Y entire installation may be preserved. This last mentioned arrangement, shown in this application, has also been specifically shown and described and claimed in said pending application.

By the means hereinbefore described and hereinafter claimed, exemplified in a coke oven of the general construction herein indicated, I have provided means whereby the cracking of the adjacent walls is reduced to a minimum.

What I claim is:

1. In a coke oven, the combination with a combustion chamber having its side walls constructed of joined elements; of a partition wall contiguous to one side of said combustion chamber and also constructed of joined elements, the elements of both of said walls being arranged to extend in different directions, whereby the joints of the respective walls will lie in planes intersecting each other.

2. In a coke oven, the combination with an inclined combustion chamber having vertical side walls constructed of joined elements, the joints formed by said elements extending in the direction of generalV inclination of the chamber and at right angles thereto; of a partition wall contiguous to one wall of said combustion chamber and also constructed of joined elements, the joints formed by the latter being horizontal and at right angles thereto. Y

3. In a coke oven, the combination with a pair of combustion chambers; of a partition wall disposed therebetween, saidwall and those sides of said chambers contiguous thereto being constructed of joined elements, the elements of said wall being arranged to extend in directions different from those in which the elements of the sides of said chambers extend, whereby the joints of adjacent walls will lie in planes intersecting each other.

4. In a coke oven, the combination with a pair of inclined combustion chambers; of a partition wall disposed therebetween, those sides of said chambers contiguous to said wall being constructed of joined elements whose oints extend in the direction of genoral inclination of the chambers and at right angles there-to, said partition wall being also constructed of joined elements, the joints of the latter, however, being horizontal and at right angles thereto.
